Recommended 5th Wheel Upgrade. When increasing the rolling diameter of your Jeep Wranglers tires it is recommended to upgrade your spare tire at the same time as the stock spare may be too small to be used. And besides a big meaty spare looks intimidating on the back of your Wrangler.

5 Top Rated Questions

what is the offset and/or backspacing of this wheel? does the 17" wheel have the same backspacing as the 16"

Hello, on the Mammoth Boulder Beadlock Style Black Wheel - 16x8 (07-17 Wrangler JK) the Backspacing is 4.5" (114mm) and the Offset is 0mm (0") the 17 inch wheel has a Backspacing of 4.7" (121mm) and Offset of -6mm (-0.2")

Thank you for your question! A 285/70R17 is about 32.7" tall and about 11.2" wide. With this wheel you will have enough backspacing that you will not need spacers. At full flex with no lift I would not recommend an almost equivalent 33" tire because there will be interference with stock fenders.

If your looking to run a 33x12.5R16 you would want to run a 305/70R16 tire. The benefit for running a larger tire is when airing them down for heavy off roading, and it can provide a softer ride feel on roads.

These wheels are pushed out further to provide a greater level of stability on a lifted Wrangler. If you lifted the Wrangler without going with aftermarket wheels, you'd feel a lot more top-heavy on turns.

I was looking for an inexpensive wheel to update the stock JK aluminum one. These fit the bill! They look great and have the perfect amount of offset so I was able to eliminate the 1.5 inch spacers I was running. Quality and finish got five stars for now but how they hold up long term is yet to be answered.

Excellent wheels. I’ve bought the “big brand names” in the past and these Mammoth’s live up to any other. Plus you cannot beat the price, all 4 under 500. It’s like a bogo. They look great on too!! As long as I have my Jeep these wheels will be on it.

This product is awesome. Absolutely what I expected. Shipping was fast and the product is just amazing. Very clean and just perfect. These rims give my Jeep the best look and it’s what I was looking for.

Absolutely love these, the pictures do not do justice for the color online. Not too fancy/flashy but exactly what I needed because I wasn't going to put wheel spacers on. Very close match to the Granite metallic crystal color of my JL Wrangler. I put on 315/70/17 Cooper Discoverer STT Pro

These wheels look great ! The guy at the tire shop was really impressed with the new look of my JK. The wife was a little unsure of the style (she prefers shiny polished wheels) but when she saw them on the Jeep she said it looked tough.

Quality of the wheels finish is not very good - one of them had a long hair that had been painted onto the wheel. When removed, it took some of the paint with it and left lines of raised paint where it used to be. I didn't contact ET about this, as I didn't care enough to ship it back and wait for a new one... it became my 5th wheel spare.
Paint seems "soft" - already have my first chip, with no exciting 4x4 story to tell for it - just normal road use.
Now, aside from all this - I get compliments everywhere I go, and everyone agrees they look badass.

On a whim I saw this one and went to the dealership on the same day while my wife was at work and came home with it. She was a little bit surprised (mad) to see the Jeep in t...
